This is the gold standard for multi-day backpacking. The 4-way stretch mesh fabric is 50% more moisture-wicking and 25% faster-drying than the original Give-N-Go, which means you can hand-wash these at camp and have them ready to wear again in under an hour. Reviewers who wore them on an 18-day Nepal trek report zero chafing, thanks to the flatlock seams and higher rise that prevents the waistband from rolling under a hip belt.

The bikini cut offers full glute coverage without the excess fabric of a full brief, so there is no bunching inside your hiking tights. The wide elastic waistband stays flat and doesn’t dig, even after hours of carrying a heavy pack. One reviewer noted that pantiliners don’t stick well to the mesh interior, which is a minor trade-off for the breathability.

These hold up through repeated wash cycles with minimal shrinkage, though using a dryer on high heat can tighten the fabric slightly. For serious backpackers who need one pair to last a week without a wash, the Give-N-Go 2.0 is the clear winner.

The bamboo rayon fabric used here delivers a silky, lightweight feel that is noticeably cooler against the skin than standard nylon blends. Multiple reviewers mention that this pair kept them dry during sweaty hikes in humid conditions, with no dampness or clamminess even after hours of exertion. The wide double-layer crotch gusset adds durability and a soft barrier against pack seams.

Unlike many synthetic performance briefs, these don’t trap heat, making them an excellent choice for desert hikes or summer trips where every degree of temperature regulation matters. The hipster cut sits low enough to clear most pack waistbelts, and the tag-free label eliminates one more potential scratch point.

A few reviewers note that the fabric stretches slightly throughout the day and may not hold its shape as tightly as a nylon-spandex blend. They also take slightly longer to dry than the ExOfficio mesh if you’re hand-washing at camp, but for a base-layer brief worn under hiking pants, the cooling advantage is worth the trade.

Reviewers consistently describe these as “the most comfortable underwear” and “10/10” on breathability. The bamboo rayon fabric is exceptionally soft and airy, and the wide waistband stays put without pinching. Multiple users who normally reject anything other than high-end athletic brands switched to these for daily wear and light hiking because of how well the fabric wicks moisture.

The cut is a full-coverage brief with a high waist that reaches above the belly button. This provides extra coverage under loose hiking pants, but the higher rise means the waistband may sit directly under a pack hip belt on shorter torsos. It’s important to try these before a long trek to ensure the waistband placement doesn’t create pressure.

One reviewer did report that the elastic waistband felt too tight even when the rest of the underwear ran large. The sizing runs generous, so buyers with a straight or athletic build may need to size down for a secure fit. They held shape and softness through multiple washes with no shrinkage.

The laser-cut edges on this hipster make it completely invisible under tight leggings, which is a major advantage for hikers who wear compression tights. Runners and trail runners particularly praise this model for staying put during high-impact miles, with zero bunching or visible lines. The fabric is a stretchy nylon-spandex blend that feels like a second skin.

That seamless vanishing act does come with a catch for backpacking. A significant number of reviewers report that the leg openings crawl up into the glute crease once you start moving, creating a wedgie that requires adjusting. This design works best for women with a straighter hip-to-waist ratio; curvier shapes may experience more ride-up.

For quick summit pushes or day hikes where you want zero VPL under shorts, these excel. But for multi-day treks where you can’t constantly re-adjust, the potential for a wedgie makes them a secondary choice rather than a primary backpacking pair.

The boy short cut is purpose-built to prevent thigh chafing, and this INNERSY model delivers that with a full-coverage leg that stays in place. The 95% cotton / 5% spandex blend is soft and breathable, and the 100% cotton gusset adds a natural fiber layer that many women prefer for all-day wear. Reviewers praise the lack of roll and the fact that the legs don’t ride up.

Cotton, however, is the worst fabric for moisture management on the trail. These absorb sweat and stay wet, which can lead to chafing and skin irritation once the moisture-soaked fabric rubs against the skin. For dry, low-exertion day hikes in cool weather, they’re comfortable. For any trip involving significant sweating or stream crossings, they become a weight and friction liability.

The build quality is solid, with reinforced seams that hold up through many washes. The high-waisted fit provides good coverage under hiking pants, and the colors with contrast stitching are a nice touch. If you plan to use these on trail, pair them with a moisture-wicking outer layer and change into a dry pair at camp.

For hikers who wear only leggings and want zero VPL, this seamless thong is the top contender in the mid-range. The high-waisted compression band provides tummy control and stays above the pack belt, while the seamless knit means no visible lines under tight fabric. The cotton gusset adds a soft lining that prevents irritation from the synthetic outer layer.

One of the most common complaints about thongs on the trail is ride-up and wedgie formation. The GRANKEE design largely avoids that with a wide waistband that anchors the garment in place. Multiple reviewers who switched from Victoria’s Secret note that this one doesn’t slide or shift during workouts, including strength training and hiking.

The high rise can be a problem for short torsos, where the band sits above the natural waistline of most hiking shorts. Some reviewers found that the wide elastic band created pressure on the belly at 5 months pregnant, indicating it might be too compressive for some body types. Sizing up is a safe bet if you’re between sizes.

The Reebok boyshort offers a 4-inch inseam, which provides longer leg coverage than most boy short styles. This reduces friction between the thighs and can prevent chafing during long hikes. The seamless tagless waistband is comfortable and stays flat under a pack belt, and the stretch performance fabric moves with the body without binding.

The primary trade-off for the lower price point is longevity. Multiple reviewers report that the fabric stretches out over time and loses its original snug fit after several wears. This means the anti-chafe benefit of the longer leg can diminish as the elastic degrades, potentially leading to bunching. One reviewer noted they should have bought a size smaller.

If you’re on a tight budget and need a 5-pack for weekend trips, these deliver acceptable performance for the cost. They wash well without shrinking or fading, and the multiple color options are a nice bonus. Just expect to replace them more frequently than the nylon-spandex premium models.
